How to Read the Call Numbers - cont.

The first step is the easiest. Putting he first letters in correct order you get this:

M 1613.3 .B94 L6 1990Z

PK 2198 .G4 A233 1999

PN 1994 .M78 1996

PS 2552 .O874 A6 2001

PS 3568 .A486 W56 2001

PS 3 .A47 1967

The next step is a little more tricky. The first set of numbers you come to are treated as a WHOLE number, and shelved in order from smallest to largest. So... 3 is before 2552 which is before 3568, which means PS 3 is before PS 2552 which is before PS 3568.
